Belt Tensioner 38158

The Gates 38158 belt tensioner is an automotive component designed for light-duty belt systems. It maintains correct belt tension to support reliable operation of accessories such as alternators and water pumps. Professional technicians and vehicle owners use it during scheduled maintenance or when replacing worn tensioner assemblies. The unit carries industry number 38158 for straightforward cross-referencing.

Thermal and power characteristics

The tensioner operates passively within the engine accessory drive and does not draw electrical power. It produces no audible noise beyond normal belt contact and generates no measurable heat of its own. California Proposition 65 notices indicate the product contains chemicals known to the state to cause cancer and birth defects or other reproductive harm. No additional thermal or acoustic data is provided.

Included hardware and compliance

The package supplies the tensioner assembly only; no mounting bolts, belts or tools are included. The California Proposition 65 warnings apply to the product as supplied and do not change with installation.

Questions about this item

How do I install the Gates 38158 belt tensioner and what step is often missed?

Mount the tensioner to the engine bracket, route the belt, then apply the correct torque to the pivot bolt; the step often missed is using a torque wrench to meet the manufacturer's specification.

What maintenance or replacement will the Gates 38158 belt tensioner need later?

Inspect the pulley bearing for noise and the arm for smooth movement at each belt change; replace the unit if the spring loses tension or the pulley wobbles.

What limit appears first on the Gates 38158 belt tensioner under sustained use?

The spring fatigue limit is reached first, causing the tensioner arm to lose its ability to maintain proper belt tension over time.
